Thermo Nicolet iS50 bench FTIR spectrometer
Fourier Transform Infrared (FTIR) spectroscopy is used to identify and analyse minerals, organic and man-made materials.
How it works
Infrared radiation is passed through the sample.
A detector is used to measure either the amount of radiation transmitted through or the amount of radiation reflected from the sample.
The resulting spectrum provides a unique chemical fingerprint of the sample.
Infrared spectroscopy is commonly used for the non-destructive identification of unknowns, the characterisation of bonds present in samples, and the detection of additives or contaminants.
Measurements taken over time can be used to extract kinetic information, as the spectral shapes and proportions will change with time.
